Public safety agencies, transit systems, utilities, and amateur radio operators have migrated from analog FM to digital protocols like P25 (Phase 1 and 2), DMR (Digital Mobile Radio), NXDN, and TETRA. For radio hobbyists, researchers, and interoperability developers, decoding these digital voice streams requires specialized software that can demodulate the complex digital modulation schemes and reconstruct intelligible audio.</p> https://www.pistack.xyz/posts/2026-06-05-self-hosted-ham-radio-digital-voice-svxlink-mmdvm-freedv-guide/ Fri, 05 Jun 2026 00:00:00 +0000 https://www.pistack.xyz/posts/2026-06-05-self-hosted-ham-radio-digital-voice-svxlink-mmdvm-freedv-guide/ <h2 id="introduction">Introduction</h2> <p>Amateur radio has evolved far beyond analog voice. Today&rsquo;s ham radio operators use digital voice modes, IP-based repeater linking, and software-defined radio to build global communication networks — all from a self-hosted Linux server in the shack. Whether you&rsquo;re running a repeater site, building a digital voice hotspot, or experimenting with HF digital modes on a Raspberry Pi, open source software makes it possible.</p>
